Answer:
Step-by-step explanation:
Seperate it into two pieces;
Piece 1, base of 2, height of 9
Piece 2, base of 8, height of 5.
Area of Piece 1:
A = bh
A = 2 (9) = 18
Area of Piece 2:
A = bh
A = 8 (5) = 40
Add the areas of both pieces:
18 + 40 = 58 m2
For this problem,we use the Fundamental Counting Principle. You know that there are 7 digits in a number. In this principle, you have to multiply the possible numbers for every digit. If the first number cannot be zero, then there are 9 possible numbers. So, the value for the first digit is 9. The second digit could be any number but less of 1 because it was used in the 1st digit. So, that would be 10 - 1 = 9. The third digit must be the value in the second digit less than 1. That would be 9 - 1 = 8. And so on and so forth. The solution would be:
9×9×8×7×6×5×4 = 544,320 7-digit numbers
The opposite of 12 is -12 . To add negative<span> numbers to </span>positive<span> numbers count backwards, as if you were subtracting. We have the problem: 1+ (-12). This can be read as “one </span>plus negative<span> twelve.” This can also be read as 12-1 which is 11 so the answer is 11.</span>
